Captain's log - Stardate 2261.387
As we left the planet the portal is on, Spock mused about whether or not we had altered or created a new timeline by our actions. I told him that as far as I'm concerned, all other parallel timelines can look out for themselves. I wasn't about to leave that damn portal open to be used. After all, if Bones caused such a wide reaching change just by getting married, I don't even want to imagine the damage that could be done by someone deliberately going back and changing the past.
